In this study, researchers observed that Keratin 15 expression in hairfollicles was significantly higher in normal adult men compared to those with androgenetic alopecia.

This study suggests that allergens like linalool found in personal care products may contribute to the pathobiology of frontal fibrosing alopecia by affecting immune responses and stem cell function in hairfollicles.

This study found that women with androgenetic alopecia demonstrated higher androgen receptor gene expression compared to controls, with a correlation found between higher AR expression and fewer CAG repeats in the AR gene.
The conversation discusses that dutasteride may be more effective than finasteride for frontalhair loss due to higher 5ar Type 1 enzyme activity in that area. Some users question the validity of this information, while others confirm it with additional sources.
The user is considering a hair transplant for frontal temple density but is concerned about shock loss. They have been using finasteride for about two years and are advised to consider minoxidil and microneedling for better results.
Reducing scalp DHT doesn't directly correlate with preventing hair miniaturization, as different follicles have varying sensitivity levels. Dutasteride at 0.5 mg and 2.5 mg shows minimal visual difference in hair regrowth, with side effects being a consideration for higher doses.
A permanent hair loss solution could involve reprogramming hairfollicles to resist DHT using mRNA and siRNA. However, high costs, safety concerns, and the pharmaceutical industry's preference for ongoing treatments over one-time cures are major obstacles, with finasteride and minoxidil remaining standard treatments.
Japanese scientists discovered ABM cells, enabling successful human hairfollicle cloning, potentially curing hair loss. The treatment may be available in Japan by 2028, but it will be expensive and require travel.
Hair transplantation moves DHT-resistant follicles from a donor area (back and sides of the scalp) into thinning or bald areas. The transplanted hair is generally permanent, though surrounding native hair can keep thinning.
